Carine Roitfeld let loose on the first night of New York Fashion Week, perhaps because she doesn’t have to attend the shows after stepping down as editor-in-chief of French Vogue last month. At the after-party for her son Vladimir‘s exhibition for graffiti artist RETNA, Roitfeld danced on a banquette at Indochine along with her daughter, Julia, while partygoers including Mary-Kate Olsen, Lily Donaldson, Vito Schnabel, Fabiola Beracasa, Olivier Zahm, Carlos Souza, Carlos Mota and Nur Khan looked on.
